But notice the limitation of quantum computers, if it has N qubits it takes 2^N complex numbers to specify its state, BUT you can only retrieve N bits of information from it (c.f. Holevo's theorem). So it doesn't really act like 2^N parallel computers.OK, but nobody pretended the contrary. You can still extract N bits depending on the 2^N results, by doing some Fourier transfrom on all results obtained in "parallel universes". This means that the 2^N computations have to occur in *some* sense.But they pretend that the number 2^N is so large that it cannot exist in whole universe, much less in that little quantum computer and therefore there must be other worlds which contain these enormous number of bits. What Holevo's theorem shows is the one can regard all those interference terms as mere calculation fictions in going from N bit inputs to N bit outputs.Can such "calculation fictions" support conciousness? That's the real question. Ifthey can, then you can't avoid many-worlds (or at least many minds).

`Why is that "the real question"? Saying yes to the doctor implies that a classical`

`computer can support consciousness.`
